Every time your class has occasion to pass from the room, take the same
stand by the door, leading into the hall. Then say, “First row, please
pass! Second, third!” etc. When the last line has left the room, take
another permanent stand in the hall, where you watch the children to see
that they keep in a straight line and march in an orderly fashion from
room to room.
If one or two should “forget” to be quiet, speak to them while in line.
“John, remember the rule for marching in absolute order.”
